qcacmn: Fix dp wifi3.0 documentation

The kernel-doc script identified a large number of kernel-doc issues
in the dp/wifi3.0 folder. A series of patches have addressed most of
the issues, so now fix the remaining issues. Just like in the previous
patches, there are a number of instances where public functions have
their implementation documented instead of having their interface
documented, so make sure that the interfaces are documented.
